Saggital view of mouse brain cerebellum at postnatal day 219. Several Purkinje cells (red) are labeled with antibody against calbindin. GABAergic synaptic vesicles (green) are labeled with antibodies against the vesicular GABA transporter protein (VGAT). Nuclei (blue) are labeled with the nuclear marker Topro-3. There is a strong accumulation of VGATpositive vesicles around the cell bodies of Purkinje cells. Confocal image was taken with a 60x objective.
